Peter walks 3 minutes at a constant rate and travels 330 meters. if we graph this relationship with time along the x-axis and distance along the y-axis, the slope of the line representing this relationship is

Slope = 110

Step-by-step explanation:

We have been given that Peter walks 3 minutes at a constant rate and travels 330 meters.

We know that slope of a line is known a s rise over run, so we can represent our given information as:

Therefore, the slope of the line representing this relationship is 110.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
